Kanye West’s The Life of Pablo is a work in progress. The hip-hop mogul continues to tinker with his latest album, which received two updates today.

Sia and Vic Mensa once again appear on “Wolves.” The song, which he debuted a year ago at his Yeezy fashion show and on “SNL,” originally featured the singer and rapper. But when TLOP was released in February, they were missing in place of Frank Ocean.

But Ocean fans shouldn’t be worried. The singer’s contribution to “Wolves” is now separated into its own 38-second song, aptly titled “Frank’s Track.”

According to Kanye, he has been working on the changes for the last three weeks. “Life Of Pablo is a living breathing changing creative expression. #contemporaryart,” he tweeted.

Fixing Wolves 2day… Worked on it for 3 weeks. Life Of Pablo is a living breathing changing creative expression. #contemporaryart
